IMPROVEMENT IN LOOM-PICKERS.

Specification forming part of Letters Patent No. 192,482, dated June 26, 1877 application filed J une 3, 1875.

To all lwhom It may concern Be it known that I, JOHN W. BARLOW, of Lawrence, Essex county, State of Massachu setts, have invented an Improvement in Manufacture ot' Staff-Pickers for Looms, of which the following'is a specification:

This invention relates solelyr to staff-pickers Y for looms; and it consists in the manufacture ofstaff-pickers from strips of leather, or of rawhide, or of both leather and rawhide, and a sheet of leather or of rawhide, by tirst doubling and folding the said sheet over and about `the said strips, and then molding and press` ing the same into proper shape, and then riveting or otherwise securing the whole together, all substantially as hereinafter described,

whereby great eiciency, strength, and durability are given to a staff-picker, as will hereinafter fully appear.

In the accompanying` Aplate of drawings, Figure 1 is aface view of a staf-picker made according to this invention; Fig. 2, a section on line w w, Fig. l; Fig. 3, a section on line a: x, Fig. l; Figs. 4 and 5, views illustrative of the separate strips and ofthe sheet before the latter is doubled and folded about the frame.

In the drawings, AA represents a staff-picker which corresponds in shape and outline to staff pickers as ordinarily made. This stati'- picker A is made from a :dat sheet, B, and two strips, (l G2, all or either (more or less) of which may be of leather or ot' rawhide. Tile two edges D and E of the sheet B are cut in an outline corresponding to the outline ofthe edge l of the picker A, and the edgep of each of the strips G G2 is cut in an outline correspending to edge l of picker A, and the edge g of each of the strips C C2 is eut in an outline corresponding to edge m of picker A. The two strips C C2 are laid atwise against one surface of the sheet B, with the edge p of the one, C, coincident with one edge, D, of the sheet B, and the corresponding edgep of the other, G2, coincident with the other edge, E, of the sheet B, and in this position they are then both tacked or otherwise secured to the sheet B againstaccidental displacement during the fold and double of the sheet about them, as hereinafter described.

Midway between the two strips C C2 the sheet B is grooved, as at F, in a line parallel to the general direction of its two edges D E. The general width of the sheet B between the two edges q of the strips C C2 that are toward each other in their before-described location upon' the sheet B is such that, by twice doubling the sheet B, prepared with strips O O2, as before stated, over from each of its edges D E toward the center, said two edges D E will then lie against its central groove F and alongside each other, and the two strips C O2 be separated by a double thickness of the sheet, and also covered by the sheet B at their two edges, and also at each side or surface.

After folding and doubling the prepared sheet B, as above described, it is then placed in a mold of a form corresponding to the shape of the picker shown in Fig. l, and subjected to a pressure sucient to wholly and compactly press it into the shape of the mold, and then, being removed from the mold, thewhole is riveted together in the direction of its thickness, the same as in the manufacture of staffpickers from a series of separate and distinct layers, as heretofore practiced.

Before folding the prepared sheet B and pressing it with its strips C G2, as hereinabove described, it is best to soften the whole by soaking it in water.

A staff-picker made as hereinabove described is found to be, in efficiency, strength, and durability, far superior to staff-pickers as heretofore made; and these results are secured because of the peculiar inelosing or covering of the layers C G2, herein described, from the doubling and folding of the sheet B, as described.

The groove F of the sheet B facilitates the molding of the sheet B to the form ofthe edge l of the picker, and the correspondence in shape at the edges D E of sheet B and the edges p q of strips C C2 with the edges l and m of the completed picker A, as herein particularly described, secures, under the molding and pressing operation, a perfect and complete, solid and compact, picker in all its parts and outlines.

I am aware that it is not new to make loompickers by an interlocking fold of a single sheet, as such is shown and described in the Letters Patent issued to Albert Holbrook,

Fercal doubled over and into the groove F and riveted together, als and for the purpose described.

The above specification of my invention signed by me this 13th day of May, A. D. 1875.

JOHN W. BARLOW.
